Abstract
The present invention provides novel systems, methods, and processes for producing and synthesizing, through cost-effective thermal processes, highly active and stable carbide-based nano-structured catalysts and compositions that can be used in dry reforming of methane, natural gas, and biogas, for example, to synthesis gas (syngas). The invention provides for using carbon-containing raw materials for synthesizing and producing carbon-encapsulated metal-core nanoparticles such as nickel-based, tungsten-based, and molybdenum-based nano-structured catalysts that can be used in dry reforming gas to syngas.
